E2b actions 27

Every E2b action below is a callable tool any Definable persona can invoke.

Connect to Sandbox

Tool to connect to an existing E2B sandbox and retrieve its details. Use when you need to reconnect to a sandbox from different environments or resume a paused sandbox. The TTL is extended upon connection.

Create Template

Tool to create a new E2B template with specified configuration. Use when you need to define a new sandbox template that can be used to spawn sandbox environments.

Create Webhook

Tool to register a new webhook to receive sandbox lifecycle events for the team. Use when you need to set up notifications for sandbox lifecycle events such as creation, updates, or termination.

Delete Sandbox

Tool to terminate and permanently delete a running E2B sandbox instance. Use when you need to kill a sandbox that is no longer needed. Once terminated, the sandbox cannot be resumed.

Delete Webhook

Tool to unregister a webhook and stop receiving lifecycle events. Use when you need to remove a webhook that is no longer needed or to clean up webhook registrations.

Check API Health

Tool to check the health status of the E2B API. Use when you need to verify that the API service is operational and accessible.

Get Sandbox

Tool to retrieve detailed information about a specific sandbox by its ID. Use when you need to check sandbox status, metadata, or configuration details.

Get Sandbox Logs

Tool to retrieve logs from a specific E2B sandbox instance. Use when you need to debug or monitor sandbox execution by viewing its console output and system logs.

Get Sandbox Lifecycle Events

Tool to retrieve the latest lifecycle events for a particular sandbox instance. Use when you need to track state changes including creation, pausing, resuming, updates, and termination of a sandbox.

Get Sandbox Metrics

Tool to retrieve timestamped CPU, memory, and disk usage metrics for a sandbox. Use when you need to monitor resource usage of a running sandbox. Metrics are collected every 5 seconds; returns empty array if no metrics available yet.

Get Team Metrics

Tool to retrieve timestamped CPU, memory, and disk usage metrics for a team. Use when you need to monitor aggregated resource usage across all sandboxes belonging to a team.

Get Team Maximum Metrics

Tool to retrieve the maximum value for a specific team metric in a given interval. Use when you need to check team limits or peak usage, such as maximum concurrent sandboxes allowed or highest resource usage.

Get Template Build Status

Tool to get the status of a template build. Use when you need to check the build status of a template that was started asynchronously. Useful in polling loops to monitor template builds in progress.

Get Template Files

Tool to get an upload link for a tar file containing build layer files. Use when you need to retrieve or download template build layer files by their hash.

Get Webhook Configuration

Tool to retrieve the current webhook configuration for a specific webhook. Use when you need to inspect webhook settings, verify configuration, or check webhook status.

List All Sandboxes

Tool to list all running and paused sandboxes associated with your team. Use when you need to view active sandboxes, monitor sandbox state, or retrieve sandbox identifiers for further operations. Supports pagination and filtering by state or metadata.

List Sandboxes Metrics

Tool to retrieve timestamped CPU, memory, and disk usage metrics for multiple sandboxes. Use when you need to monitor resource usage across multiple sandboxes simultaneously. Metrics are collected every 5 seconds; returns empty array if no metrics available yet.

List Team Sandbox Lifecycle Events

Tool to retrieve the latest lifecycle events across all sandboxes associated with the team. Use when you need to monitor sandbox activity, track lifecycle changes, or audit sandbox operations.

List All Templates

Tool to list all available E2B templates for your team. Use when you need to view available templates, retrieve template identifiers, or audit template configurations.

List All Webhooks

Tool to retrieve all registered webhooks for your team. Use when you need to view all webhook configurations, audit webhook settings, or manage multiple webhooks.

Pause Sandbox

Tool to pause a running E2B sandbox preserving its filesystem and memory state. Use when you need to temporarily suspend a sandbox while maintaining its state for later resumption. Takes approximately 4 seconds per 1 GiB of RAM to pause. Paused sandboxes can be stored for up to 30 days.

Create Sandbox

Tool to create a new E2B sandbox from a template. Use when you need to launch a fresh sandbox environment for code execution, testing, or development purposes.

Set Sandbox Timeout

Tool to set the timeout for an E2B sandbox. Use when you need to extend or reduce the sandbox lifetime. The timeout is measured from the current time, and calling this multiple times overwrites the previous TTL.

Refresh Sandbox

Tool to refresh an E2B sandbox and extend its time to live. Use when you need to keep a sandbox alive longer and prevent it from timing out.

Start Template Build

Tool to start a build for an E2B template. Use when you need to initiate the build process for a template with specific configuration. The build runs asynchronously and returns immediately with a 202 Accepted status.

Update Template

Tool to update an E2B template configuration. Use when you need to modify template settings such as changing visibility (public/private status).

Update Webhook Configuration

Tool to update an existing webhook configuration including URL, enabled status, and subscribed events. Use when you need to modify webhook settings, change the destination URL, enable/disable a webhook, or update event subscriptions.

Frequently asked questions

What can I automate with E2b on Definable?

Anything E2b exposes through its API. Common developer tools workflows on Definable include triage issues, review pull requests, monitor builds. Personas can call any of the 27 E2b tools directly, then chain the result into another integration without you writing code.

How does E2b authentication work?

E2b uses API_KEY on Definable. You connect once from the integrations page, scoped to the permissions you choose, and from then on any persona that has the integration enabled can act on your behalf. Tokens are encrypted at rest and rotated automatically.

Is the E2b integration included in my Definable plan?

Yes — every Definable plan, including Starter, includes access to all 27 E2b tools. You only need a separate E2b subscription if E2b itself charges per seat or per API call.

Is using E2b through Definable secure?

Every call from a persona to E2b is logged with the user, persona, prompt, and response. Tokens never leave Definable's secrets vault, scopes are configurable per persona, and you can revoke access at any time from the integration page.

How do I get started with E2b on Definable?

Sign up for Definable, open the integrations page, find E2b, and connect via OAuth or API key. You can immediately attach E2b to any persona and start running workflows. The free Starter plan includes 5,000 credits/month.

What E2b actions does Definable expose?

Definable exposes all 27 E2b actions as callable tools — including `Connect to Sandbox`, `Create Template`, `Create Webhook`, plus 24 more. Each tool gets a typed parameter schema so personas know exactly how to call it.
